When feeling the top of the stove the left side is much cooler than right. Doesn't matter what the fan speed is, always more air blowing out the left compared to the right.
Should the air be blowing out evenly across the front of the stove? The dealer who installed it is stopping over tomorrow to check/set the power venter setting, but I thought I would check to see what people had to say on here.
You sound like a perfectionist like me. We should feel sad for ourselves.
Here comes the engineering explanation....sigh....
The side on the opposite side of the fan will naturally flow less since the distance the air in the cavity has a longer path and with that, air to surface friction occurs (that Reynolds # stuff) with consideration for varying distances...in other words, it takes more pressure to move the air to the side opposite the fan side...however, the air takes the path of less resistance, which is the side of the fan. Same thing happens when one of the two convection fans is unplugged on the Pocono.
A big deal ? Well, if you really sharpen the BTU pencil, the side of the stove that does not flow as much likely has a higher metal surface temp compared to the side that flows more. Convection (how much heat the air absorbs from the surface) is related to the delta T between the air and the metal surface). I agree based purely on heat transfer logics that you optimally want the air to flow over ALL the hottest metal possible for maximun heat transfer .
Your stove also uses a 265 cfm blower, a lot more cfm that many other similar stokers, so you are getting a lot of convection regardless of your concern. Also, this "blower on one side'/less flow on other side" is likely common on many stokers , not just LL. Its fluid dynamics.
Respectively offered, potentially on the Pioneer an internal metal flow guide directing a portion of the air to the side opposite the fan could possibly be crafted and welded in place at the optimal location during the manuf process to equalize the flow on both sides of the stove. It would likely not affect the cert of the stove as an argument could be made that the guide is merely equalizing the firebox temp accross its entire surface.
One other thing to really consider. A beer. After a beer with the temp 0 F outside sit barefoot in front of your stove , focus on the blue flame and consider how intelligent you were in picking the most reliable and maintenance free stoker on the market .
